chromophoric capabilities deriving from a conjugated, chelating
framework. Reported here are tricoordinate copper(I), silver(I), and
gold(I) complexes of a tetraphenylazadipyrromethene ligand. The
new complexes are characterized by optical absorption and
emission spectroscopy, multinuclear NMR, mass spectrometry,
elemental analysis, and X-ray diffraction crystallography. Time-dependent density functional theory calculations indicate that the
principal absorption features in azadipyrromethene complexes result
from optically allowed intraligand transitions that undergo configuration interaction.
